It shouldn't have any negative consequences. It appears from the context to 
have been added as bounds checking, i.e. ensuring that the number of channels 
doesn't exceed the limits of a channels array in either direction. < 0 and > 
MAX_CHANNELS would definitely be outside any array, but it's unlikely that zero 
would and you're testing backs this up - it's not crashing.

This check didn't even exist in 0.25 and so it seems entirely safe to make the 
change that I did. I'm guessing that the person who added the check in the 
first place just assumed that since a zero channel audio stream would be 
useless throwing an error at this point made sense.
